What Game Review does
Chess.com Game Review runs your finished game through the Stockfish engine, grades every move (from Brilliant and Best down to Mistake and Blunder), gives each side an accuracy percentage and an estimated rating for the game, and points you to the moments that decided it. It is the polished, colour-coded report many players love.
How it is computed
The analysis is done in the cloud, on chess.com's servers, which is powerful but expensive to run. That cost is why full Game Review sits behind a paid (Diamond) membership, and why free members are limited to a single review per day.
What the labels mean
The move grades come from the same engine ideas used everywhere: how much evaluation each move lost, whether a strong move was also a sacrifice, and whether a move was forced. If you want the details, see what is a brilliant move and blunder vs mistake vs inaccuracy.
